modelBrush
Model considering voltage drop of carbon brushes
Extends from Modelica.Electrical.Polyphase.Interfaces.TwoPlug (Component with one polyphase electrical port), Modelica.Thermal.HeatTransfer.Interfaces.PartialConditionalHeatPort (Partial model to include a conditional HeatPort in order to dissipate losses, used for graphical modeling, i.e., for building models by drag-and-drop).
Information
Model of voltage drop and losses of carbon brushes. This three-phase model uses three DC Brush loss models.
